Fox News reported that according to American authorities, Tamerlan Tsarnaev, who performed the Boston Marathon bombing together with his younger brother and was later killed by law enforcement officers, wrote a text message to his mother saying that he is willing to die for Islam.

Earlier it was reported that the elder brother was added to the CIA's terror suspects list over a year ago, but further inquiry at the time did not reveal any links to terror groups. (Ynet)
